Abstract

This study compared the performance of microalga growth, nutrient removal, algal organic matter, and energy storage products in mixotrophic, photoautotrophic, and heterotrophic conditions. Scenedesmus obliquus was used as a model species. Mixotrophic condition showed the highest specific growth rate of 0.96 d⁻¹ as well as the fastest nitrogen and phosphorus removal rate of 85.17 mg-N g-cell⁻¹ day⁻¹ and 11.49 mg-P g-cell⁻¹ day⁻¹, respectively, compared with photoautotrophic and heterotrophic conditions. Mixotrophic microalgae had relatively higher carbohydrates and lipids contents (21.8 and 24.0%) than photoautotrophic and heterotrophic conditions. Meanwhile, algal organic matter (AOM) in the medium was produced at the highest level under photoautotrophic condition. Mixotrophic condition was more efficient in terms of microalga growth, nutrient removal, production of energy storage products, and suppression of AOM, and would be adaptable for wastewater treatment process.
